For the homework, choose a basic recipe with 3-5 ingredients and very simple instructions. Replace the "" with the appropriate code to get the desired information from the user and store it in the right variable.
import java. util. Scanner;
public class Recipe {
public static void main (String[] args){
Scanner scan = new Scanner (System. in);
// Information about recipe
String title, instructions;
// Variables to be used (and reused)
// for each ingredient
double amount;
String ingredient;
String units;
// Each variable will be a string containing
// the name, amount, and units for one of the
// ingredients in the recipe. You may need more
// or less such variables, depending on how many
// ingredients your recipe has.
String ing1, ing2, ing3;
int component = 0;
// Get recipe title from user
System. out. print("What is this recipe called? ");
// Note that the next 8 lines will repeat
// a number of times, depending on how many
// ingredients your recipe has. The main thing
// that will change each time is the seventh
// line: ing1, ing2, ing 3, etc.
System. out. print("Ingredient #" + ++component + ": ");
System. out. print("How many? ");
System. out. print("What units? ");
ing1 = amount + " " + units + " of " + ingredient;
System. out. println();
// Second ingredient
System. out. print("Ingredient #" + ++component + ": ");
System. out. print("How many? ");
System. out. print("What units? ");
ing2 = amount + " " + units + " of " + ingredient;
System. out. println();
// Third ingredient
System. out. print("Ingredient #" + ++component + ": ");
System. out. print("How many? ");
System. out. print("What units? ");
ing3 = amount + " " + units + " of " + ingredient;
System. out. println();
// Add more code here to get fourth and fifth
// ingredients, if needed.
// Ask user for instructions. When user types out
// instructions and presses enter, you will get them in
// a string and save it to the appropriate variable
System. out. println("Please enter the instructions:");
System. out. println();
System. out. println("###" + title + "###");
System. out. println("Ingredients (" + component + " total): ");
System. out. println("* " + ing1);
System. out. println("* " + ing2);
System. out. println("* " + ing3);
System. out. println("Instructions: \n" + instructions);
}
}
